Amaze your friends with the ability to find anything you command the "detector" to find!
1) Launch the Pocket Detector application.
2) Loudly tell the "detector" what to find, i.e. "Find my keys."
3) Subtly place your thumb in the lower-left corner of the screen.
4) As you sweep your iPhone across the room, slowly move your thumb across the bottom of the screen.
5) Embellish as needed for desired effect.
NOTE: This is a novelty application, and does not actually detect anything whatsoever. Except maybe gullible friends and family members.
